Hi! Epson sets the standard (I think) for scanners. We have a jumbo deluxe model at work and all the techies swear by it. At home I have an Epson also. Some features I like about my home model are: separate ink wells. That way if you run out of one color, you aren't replacing the entire cartridge that's full of the other colors. The lid is not 'fixed.' Meaning it has some give to it on some type of hinge thing so if you put a book or lumpy card on it, the lid still lays flat on the document/book/card. Finally, the price was right--about $150ish at Sam's Club. Santa brought it to me!
Go here to read up on scanners before making your choice:

You will learn about prices, reviews and how a scanner works. I thought it was pretty good information for the laywoman! Good advice they gave was to make sure your computer has the 'guts' to handle the scanner.
GL with your scanning!
